Let G=(V,E) be a simple graph. The energy of G isthe sum of absolute values of the eigenvalues of its adjacencymatrix A(G).In this paper weconsider the edge energy of G (or energy of line of G) which is definedas the absolute values of eigenvalues of edge adjacency matrix of G. We study the energy for the line of specific graphs.
